Following the first trailer that debuted earlier this month, HBO has debuted the full-length trailer for the upcoming comedy special 7 Days in Hell with even more revealing and hilarious footage. Starring Andy Samberg (Brooklyn Nine-Nine, Saturday Night Live) as Aaron Williams and Kit Harington (Testament of Youth, HBO's Game of Thrones) as Charles Poole, the HBO special presentation 7 Days in Hell debuts Saturday, July 11 (10:00-10:45 p.m. ET/PT). Prior to its debut on the main HBO channel, 7 Days in Hell will be available on HBO NOW and HBO GO, starting July 8.

They were two of the biggest tennis stars of their day: Aaron Williams, a hyper-malcontent American bad boy, and Charles Poole, a dim-witted prodigy who carried England's hopes for a championship on his shoulders. In 2001, these sworn archrivals met for the longest and greatest tennis match of all time: a seven-day, five-set marathon that took literally everything out of them. Also appearing in 7 Days in Hell are Fred Armisen, David Copperfield, Lena Dunham, Chris Evert, Will Forte, Karen Gillan, Filip Hammar, Jim Lampley, Howie Mandel, John McEnroe, Soledad O'Brien, Michael Sheen, Mary Steenburgen, June Squibb and Serena Williams.
